We report a rare case of giant cell tumor (GCT) of the sternum in a 55-year-old man. He presented with a bony mass in the body of the sternum that had been slowly growing over 6 months. The patient was treated by surgical curettage and cementation. Histological study showed typical GCT findings with cytogenetic abnormalities of many telomeric associations of chromosomes, predominantly the 19q arm.

Abstract The objective of this work was to measure the tooth root canals’ diameter, remnant dentin thickness, endodontic post distance, and resin-matrix cement layer after three types canal shaping. Thirty extracted human premolars were endodontically treated groups specimens divided according cementation with two different posts as follow: A) Fibio Fiberglass Post™, Anthogyr, France; B) multi-...

Abstract Bio-cementation through bacterial mineralization can be considered an “eco-friendly” solution for soft or loose sandy soils, particularly in ground slopes and high rainfall zones, to achieve sustainable development goals. Using urelytical bacteria with the ability decompose urea calcium carbonate precipitation selected as primary agent bio-cementation process. This study clarifies effe...

PURPOSE Optical coherence tomography (OCT) has been investigated as a novel diagnostic imaging tool. The utilisation of this equipment has been evaluated through several studies in the field of dentistry. The aim of this preliminary study was to determine through basic experiments the effectiveness of OCT in implant dentistry. MATERIALS AND METHODS To assess detection ability, we captured OCT...

OBJECTIVES This study aimed to compare the incidence of white spot lesions (WSLs) around orthodontic bands following the application of two glass ionomer (GI) cements namely GC Gold Label and GC Fuji Plus for six to 12 months. MATERIALS AND METHODS A total of 186 permanent first molars of orthodontic patients requiring banding of at least two permanent first molars were chosen. The teeth were...

The technique of cryosurgery has been used to control local recurrence in a variety of benign and malignant bone tumors. Early studies revealed significant complication rates (25%) that included fracture, infection, and soft tissue injury. Our method of cryosurgery has yielded excellent tumor control with improved complication rates. The objective of this study is to determine the characteristi...

Electrical resisivity is usually easier to measure in the laboratory and in-situ than permeability. Therefore, a method of combination between permeability and electrical resistivity might be used to define the fluid flow of reservoir rocks from resistivity data. However, estimating permeability from resistivity has been a problem examined by different authors. Furthermore, neither electrical n...

The core finishing of cast posts-and-cores after luting is routine in dental practice. However, the effects of the vibrations produced by the rotary cutting instruments over the luting cements are not well-documented. This study evaluated the influence of the time intervals that elapsed between the cementation and the core-finishing procedures on the tensile strength of cast posts-and-cores lut...
